Description

Technical Field

[0001] The present invention relates to a waterproof end plug for cleaning an ultrasonic scalpel handle, and a cleaning box having the waterproof end plug. Background Art

[0002] An ultrasonic scalpel (also known as an ultrasonic knife or an ultrasonic hemostatic knife) is an advanced medical device widely used in surgical operations. The ultrasonic scalpel can not only cut tissues but also has a blood coagulation function. During the cutting process, the high-frequency vibration of the knife head can close blood vessels, thereby reducing bleeding. The ultrasonic scalpel includes a handle and a tool. A transducer and a circuit structure are provided inside the handle, and the tool is connected to the handle. During the operation, the doctor holds the handle and inserts the tool into the human body for surgical operations. The tool is a disposable item and will be discarded after use; however, the handle is relatively expensive and is usually reused after strict disinfection.

[0003] During the disinfection process of the handle, on the one hand, it needs to be washed with water to remove surface stains, on the other hand, it needs to be disinfected in a high-temperature vacuum environment, and further, the inside of the handle needs to be disinfected. However, since the mouth of the mounting hole where the front part of the handle is connected to the tool is open, it is extremely easy for liquid to enter the inside of the handle from this mouth, resulting in damage to the circuit structure and transducer inside the handle, and greatly shortening the service life of the handle. In addition, currently, during the cleaning and high-temperature disinfection operations, it is usually necessary for manual labor to transfer it among different cleaning devices, and there is an inevitable risk of dropping during the transfer, resulting in damage to the handle. Summary of the Invention

[0056] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0057] In this article, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc. is defined with reference to the orientation corresponding to the ultrasonic scalpel handle during the cleaning process, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present application.

[0058] Refer to Figure 1 The shown ultrasonic scalpel handle 10. A transducer assembly and other circuit elements are arranged in the inner cavity of the ultrasonic scalpel handle 10. The ultrasonic scalpel handle 10 includes a handle body 102 and a connector 101 arranged at one end of the handle body 102. An installation hole is arranged on the connector 101, and a tool can pass through the installation hole and be connected to the connector 101, thereby being connected to the ultrasonic scalpel handle 10. During the cleaning process using a liquid medium, the installation hole needs to be blocked to prevent the liquid from entering the inner cavity of the ultrasonic scalpel handle 10 and damaging its internal circuit elements.

[0059] See Figures 2 to 13 the waterproof end plug 20 shown, which can be detachably connected to the ultrasonic scalpel handle 10 so as to be able to close the mounting hole on the connector 101. Specifically, the waterproof end plug 20 includes:

[0060] a plug body 1, the plug body 1 includes a plug portion 11 that can be axially inserted into the mounting hole, and the plug body 1 is also provided with a hollow channel 14 that extends axially through;

[0061] a seal 2, the seal 2 can be slidably inserted into the hollow channel 14 axially, the seal 2 has a main body rod 21 and a sealing end 22 provided at one end of the main body rod 21, and a sealing portion 15 that can axially abut against the sealing end 22 is provided in the hollow channel 14. When the sealing end 22 and the sealing portion 15 axially abut against each other, the hollow channel 14 is axially closed, and neither gas nor liquid can reach the other end from one end of the waterproof end plug 20; when the sealing end 22 is disengaged from the sealing portion 15, the hollow channel 14 is axially air-flow connected;

[0062] an expandable member 3, the expandable member 3 has a closed hollow cavity, the expandable member 3 is provided in the hollow channel 14, and the length of the expandable member 3 can change axially along the plug body 1 when expanding and contracting. One end of the seal 2 abuts against the expandable member 3 axially so that the seal 2 can be driven to slide relative to the plug body 1 when the expandable member 3 expands or contracts, so that the sealing end 22 and the sealing portion 15 are engaged or disengaged, and further the hollow channel 14 can be closed or axially air-flow connected.

[0063] Thus, after the waterproof end plug 20 is inserted into the mounting hole of the connector 101 on the ultrasonic scalpel handle 10, when the ultrasonic scalpel handle 10 is cleaned with liquid, the sealing end 22 and the sealing portion 15 can be engaged to close the hollow channel 14 to prevent liquid from entering the inside of the ultrasonic scalpel handle 10 through the mounting hole; and when the ultrasonic scalpel handle 10 is sterilized with vacuum / high-pressure gas, the expandable member 3 expands and deforms under the action of the corresponding vacuum pressure, thereby driving the seal 2 to slide relative to the plug body 1, so that the sealing end 22 and the sealing portion 15 are disengaged, and further the hollow channel 14 is opened and axially air-flow connected, and the sterilization gas can enter the inside of the ultrasonic scalpel handle 10 to thoroughly sterilize the internal parts.

[0064] See Figures 2 to 13As shown, the seal 2 further includes a pushing end 23, which is disposed at opposite ends of the main body rod 21 in the length direction with respect to the sealing end 22. The pushing end 23 always abuts against the expandable member 3 along the axial direction. Thus, as the size of the expandable member 3 changes axially, the seal 2 can slide relative to the plug body 1 accordingly, changing the mating state between the sealing end 22 and the sealing portion 15. In this embodiment, the expandable member 3 is spherical, and an arc-shaped pushing surface 23b is provided at the end of the pushing end 23 facing the expandable member 3. The arc-shaped pushing surface 23b abuts against the expandable member 3. Specifically, when arranged, the two are bonded to each other by an adhesive to maintain mutual fixation.

[0065] In this embodiment, referring to Figures 4 to 13 As shown, the pushing end 22 and the sealing end 23 are respectively connected to the inner peripheral wall of the hollow channel 14 in a sliding fit manner, and a communication channel 21a is formed between the main body rod 21 and the inner peripheral wall of the hollow channel 14 with a gap therebetween; first air holes 22a and second air holes 23a extending axially are correspondingly provided on the pushing end 22 and the sealing end 23. Here, the above-mentioned first air holes 22a and second air holes 23a both open radially outward, and each has a plurality of circumferentially spaced distributions; when the sealing end 22 is disengaged from the sealing portion 15, the first air holes 22a communicate with the second air holes 23a through the communication channel 21a to form an axially communicating air flow channel, thereby allowing the vacuum sterilization gas to pass through.

[0066] Specifically, the hollow channel 14 includes a first through hole 14a, a second through hole 14b, and a third through hole 14c that are sequentially connected in the axial direction. Among them, the aperture of the first through hole 14a is larger than that of the second through hole 14b, and the step surface formed between the first through hole 14a and the second through hole 14b constitutes the sealing portion 15. The main body rod 21 slidably passes through the second through hole 14b, and its rod diameter is smaller than the aperture of the second through hole 14b; the sealing end 22 passes through the first through hole 14a, and the outer diameter of the sealing end 22 is basically the same as the aperture of the first through hole 14a, and the two are in sliding fit; the expandable member 3 is disposed in the third through hole 14c, and the pushing end 22 extends into the third through hole 14c and is connected to the expandable member 3.

[0067] The plug body 1 is configured to be inserted into the mounting hole in the vertical direction, and the sealing end 22 is located above the main body rod 21, that is, when in use, the waterproof end plug 20 is in accordance with Figures 4 to 6 The state cooperates with the ultrasonic scalpel handle 10 to form a state as shown in Figure 21 As shown, this can prevent liquid from falling into the hollow channel 14 during the cleaning process, and after the sealing end 22 is disengaged from the sealing portion 15, this liquid enters the interior of the ultrasonic scalpel handle 10.

[0068] AsFigure 5 , Figure 6 As shown, when the sealing end 22 abuts downward against the sealing portion 15, the first air flow hole 22a is closed by the stepped surface, so that the hollow channel 14 cannot communicate axially; and when the seal 2 moves upward a certain distance, the sealing end 22 no longer abuts against the sealing portion 15, the first air flow hole 22a is not closed by the stepped surface, and it can communicate with the second air flow hole 23a through the communication channel 21a, so that the hollow channel 14 is axially air-connected.

[0069] On the circumferential hole wall of the third through hole 14c, there are also recesses 14e recessed radially outward. There are a plurality of these recesses 14e distributed at intervals in the circumferential direction. In this way, when the expandable member 3 expands, it will not completely block the circumferential hole wall of the third through hole 14c, and a channel for gas to pass through is formed between it and the recess 14e. This can avoid the problem that after the expandable member 3 expands, external gas cannot enter the upper air flow channel upward.

[0070] Referring to the figures, in this embodiment, the waterproof end plug 3 further includes a limit seat 4 disposed in the third through hole 14c. The limit seat 4 cooperates with the plug body 1 to limit the expandable member 3 in the third through hole 14c. Specifically, the limit seat 4 is disposed below the expandable member 3, so that the expandable member 3 will not fall downward from the third through hole 14c. The pushing end 22 is slidably inserted into the third through hole 14c and connected to the expandable member 3. When the expandable member 3 expands, it can only deform upward so that the seal 2 slides up and down axially.

[0071] The plug body 1 is also provided with an annular limit boss 14d. The limit boss 14d extends radially inward from the hole wall of the third through hole 14c. The limit seat 4 is supported on the limit boss 14d. The limit seat 4 is also provided with an air flow through hole 41a communicating with the third through hole 14c. The air flow through hole 41a is radially exposed outside the limit boss 14d to maintain a state of always communicating with the outside and the third through hole 14c.

[0072] Referring to the figures, the plug body 1 further includes a connecting portion 12. The connecting portion 12 is axially connected to the plug portion 11. The outer diameter of the plug portion 11 is smaller than the outer diameter of the connecting portion 12, and a stepped surface is formed between the two to limit the depth of the plug body 1 entering the mounting hole on the connector 101. At the same time, the connecting portion 12 can be held and operated by the operator and connected to other devices. On the outer circumferential portion of the plug portion 11, there is a sealing rib 13 protruding radially outward. There is one or a plurality of the sealing ribs 13 distributed at intervals axially. In this way, when the plug portion 11 cooperates with the mounting hole, a sufficient seal can be formed between the two, and it can prevent liquid from entering the inside of the ultrasonic scalpel handle 10 between the two.

[0073] Both the first through-hole 14a and the second through-hole 14b are provided in the plug portion 11, and the third through-hole 14c is provided in the connecting portion 12. This enables the expandable member 3 to be set to a larger diameter and makes it easier to expand and deform when placed in a vacuum environment, thereby driving the seal member 2 to slide up and down relative to the plug body 1.

[0074] See Figures 14 to 20 As shown, this embodiment also provides a cleaning box 30 for an ultrasonic scalpel handle. The cleaning box 30 is used to accommodate the ultrasonic scalpel handle 10 for cleaning and disinfecting it. The cleaning box 30 includes:

[0075] A box body 5 having an accommodating cavity for placing the ultrasonic scalpel handle 10 to be cleaned. A communication hole 51 communicating with the accommodating cavity is provided on the box wall of the box body 5 so that a liquid or gas supplied by an external device can enter the accommodating cavity of the box body 5 through the communication hole 51 and act on the ultrasonic scalpel handle 10 to be cleaned;

[0076] A support seat 7 fixedly provided on the box body 5 and located in the accommodating cavity. The support seat 7 has two support columns 71 arranged at intervals, and a clamping space 72 for clamping the ultrasonic scalpel handle 10 is formed between the two support columns 71;

[0077] A waterproof end plug 20 as described above. When the ultrasonic scalpel handle 10 cooperates with the box body 5, the ultrasonic scalpel handle 10 is inserted into the clamping space 72 in a mating manner and fixed relative to the box body 5. The mouth of the mounting hole faces downward, and the plug portion 11 of the waterproof end plug 20 is inserted into the mounting hole in a mating manner.

[0078] When cleaning and disinfecting the ultrasonic scalpel handle 10, first place the ultrasonic scalpel handle 10 into the accommodating cavity of the box body 5, so that the plug portion 11 is inserted into the mounting hole in a matching manner, and the ultrasonic scalpel handle 10 is inserted into the clamping space 72 with the mouth of the mounting hole facing downward, thereby being fixed in the box body 5. Place the cleaning box with the ultrasonic scalpel handle 10 to be cleaned fixed therein as a whole into the cleaning equipment, and clean it with sprayed water and cleaning liquid. The water and the cleaning liquid enter the accommodating cavity of the box body 5 through the communication hole 51 to achieve the cleaning of the exterior of the ultrasonic scalpel handle 10. During the cleaning process, the mounting hole is blocked to prevent the liquid from entering the inner cavity of the ultrasonic scalpel handle 10. Subsequently, place the cleaning box as a whole into the vacuum sterilization equipment. In a vacuum environment, the expandable member 3 expands, causing the sealing member 2 to move away from the cooperation with the sealing portion 15, and the hollow channel 14 of the plug body 1 is axially opened, so that the pressure inside and outside the ultrasonic scalpel handle is the same, and the sterilization gas can also enter the ultrasonic scalpel handle to sterilize its internal components. In the above process, the box body 5 can carry the ultrasonic scalpel handle 10, effectively protect the ultrasonic scalpel handle 10, and can be carried as a whole or automatically carried by a mechanical device, avoiding or reducing the risk of damage caused by directly dropping it to the ground.

[0079] Specifically, the box body 5 includes a box seat with an upward-facing mouth, and a box cover that can be closed on the box seat. When the box cover is closed on the box seat, the accommodating cavity of the box body 5 is closed. A locking structure 6 is also provided between the box cover and the box seat to fix the two to each other. In this embodiment, the locking structure 6 is two locking buckles provided on at least two opposite side portions of the box seat, which can be buckled on the box cover to fix the box cover to the top of the box seat. When it is disengaged from the box cover, the box cover can move relative to the box seat to open the accommodating cavity, so that the operator can place the ultrasonic scalpel handle 10 into the accommodating cavity from top to bottom.

[0080] In this embodiment, the waterproof end plug 20 and the support seat 7 are both fixed on the bottom plate of the box body 5. The waterproof end plug 20 is located between the two support columns 71. The support columns 71 extend in the vertical direction, so that the clamping space 72 is open from above. Therefore, when placing the ultrasonic scalpel handle 10 into the box body 5, it is only necessary to make the mouth of the mounting hole face downward, and when it is placed downward into the clamping space 72, the plug portion 11 of the waterproof end plug 20 is inserted into the mounting hole. Of course, in some optional operation methods, the waterproof end plug 20 can also be removed from the box body 5 first, inserted into the mounting hole of the ultrasonic scalpel handle 10 first, and then the ultrasonic scalpel handle 10 is placed downward into the clamping space 72, and the waterproof end plug 20 is inserted into the box body 5.

[0081] In this cleaning box, there is one set or multiple sets of waterproof end plugs 20 and support seats 7 that are arranged in one-to-one correspondence. SeeFigures 18 to 20 As shown, in this embodiment, it is specifically set to three groups, so that the box body 5 can accommodate and fix three ultrasonic scalpel handles 10 at the same time. These three ultrasonic scalpel handles 10 are arranged at intervals in the width direction of the box body 5 in sequence.

[0082] Referring to the drawings, the cleaning box further includes a wire winding base 8. The wire winding base 8 is fixedly arranged on the box body 5 and is located in the accommodating cavity. The wire winding base 8 is arranged at a distance from the support base 7. After the ultrasonic scalpel handle 10 is fixed to the support base 7, the power cord (not shown in the figure) on the ultrasonic scalpel handle 10 can be wound around the wire winding base 8 correspondingly, avoiding it being scattered in the accommodating cavity of the box body 5 and also avoiding the entanglement of multiple power cords with each other.

[0083] Specifically, the wire winding base 8 includes a vertical plate 81 and a winding buckle group fixedly arranged on the vertical plate 81. The winding buckle group includes a plurality of winding buckles 82 arranged in a row and at intervals from each other. In this way, the same power cord can be wound around a plurality of winding buckles 82 in sequence without forming a pile. The winding buckle group is arranged on one side or both different sides of the vertical plate 81. The number of groups of the winding buckle group is the same as and corresponds one by one to the number of support bases 7 for the power cords of multiple ultrasonic scalpel handles 10 to be wound in sequence.

[0084] When using the cleaning box provided in this embodiment to clean the ultrasonic scalpel handle 10, the waterproof end plug 20 is fixedly inserted on the box body 5 in advance. Then, the ultrasonic scalpel handle 10 is kept in a posture with the mouth of its mounting hole facing downwards. While inserting it vertically into the clamping space 72 formed by the two support columns 71, the mounting hole is correspondingly matched with the plug part 11 of the waterproof end plug 20, so that the plug part 11 is inserted into the mounting hole in a matching manner. Subsequently, the power cord is wound around the winding buckle 82 on the wire winding base 8 of the winding, the box cover is covered, and the box cover is locked on the box seat through the locking structure 6. The cleaning box carrying the ultrasonic scalpel handle 10 to be cleaned is first placed in the cleaning equipment as a whole, cleaned by spraying water and cleaning liquid, and then sent into the sterilization equipment. The inside and outside of the ultrasonic scalpel handle 10 are sterilized as a whole by using sterilization gas. During the cleaning and disinfection process, it will not cause damage to the ultrasonic scalpel handle 10 due to liquid entering the inside of the handle. At the same time, the operator can also carry it as a whole or automatically carry it through a mechanical device, avoiding or reducing the risk of damage caused by its direct falling to the ground.
